PASADENA, Calif.--(BUSINESS WIRE)--Mar. 14, 2023-- Xencor, Inc. (NASDAQ:XNCR), a clinical-stage biopharmaceutical company developing engineered antibodies and cytokines for the treatment of cancer and autoimmune diseases, today announced it will present preclinical data on novel XmAb^® CD28 bispecific antibody programs at the American Association for Cancer Research (AACR) Annual Meeting, being held April 14-19, 2023 at the Orange County Convention Center in Orlando, Florida.

“T cells in the tumor microenvironment require engagement of their T cell receptor (TCR) and their co-stimulatory receptors like CD28 to achieve full activation. This is diminished in cancer because tumor cells usually do not express CD28 ligands. We have developed an XmAb antibody platform that allows for the rapid generation of drug candidates that co-stimulate CD28 only in the presence of tumor cells and TCR engagement,” said John Desjarlais, Ph.D., senior vice president and chief scientific officer at Xencor. “We are using the platform to explore the universe of solid tumor targets, and at AACR we will present data on candidates targeting CEACAM5, mesothelin, STEAP1 and Trop-2, which have broad applicability across a range of solid tumors.”
